A day on a distant planet observed orbiting a nearby star is 41.9 hours. Also, a year on the planet lasts 48.9 Earth days.* Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth. (tried 2.315 but it was said to be wrong) Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth. (Tried 3.64, but it was also said to be wrong)
The Mars rover was deployed on the surface of Mars in July 1997. At one point during its subsequent mission, radio signals took about 9 min to travel from Earth to the rover. How far was Mars from the from Earth at that time? ___________m
